Error loading operating system

I just installed Arch and something has apparently gone wrong. I get 'Error loading operating system' write after the BIOS screen. I figure it is a problem I have created with GRUB? Any help is much appreciated.

Re: Error loading operating system

I believe this is a common error when the bootloader (eg grub) has not been installed to the MBR. In addition to installing the package and configuring it, there is a step to copy the relevant parts to the MBR (unless this is GPT, but there are similar steps there too).
